The difficulty of the invention lies in even feeding and continuous feeding.
According to the invention, a material layer is spread on the belt conveyor 1, and then the belt conveyor 1 rotates at a constant speed to feed materials uniformly; the material spreading layer mainly uses temporary storage of the pre-feeding bin 43 for raw materials, then the raw materials fall onto a belt of the belt conveyor 1 under the action of gravity through the action of gravity of the raw materials, and because three surfaces of the pre-feeding bin 43 are attached to the belt of the belt conveyor 1, the raw materials are finally presented on the belt in any shape, which is mainly realized by an open slot 44 on the right side of the pre-feeding bin 43, the raw materials in a region corresponding to the open slot 44 are kept away from the pre-feeding bin 43 at a constant speed under the friction action of the belt conveyor 1, and after the moved raw materials are lacked in the pre-feeding bin 43, the raw materials above the pre-feeding bin fall rapidly under the action of gravity; in the invention, the condition that the upper surface of the tiled material layer is uneven is further considered, and the port of the material conveying gate 2 is used for pushing and trimming the tiled material layer, so that the feeding is more uniform.

According to the invention, the distance measuring sensor 425 is arranged right above the pre-feeding bin 43, when the distance measuring sensor 425 detects that the height is lower than a preset range value, a signal is sent to the PLC control module 424, the PLC control module 424 can control the motor 423 to feed materials, when the distance measuring sensor 425 detects that the height is equal to or higher than the preset range value, a signal is sent to the PLC control module 424, and the PLC control module 424 can control the motor 423 to stop feeding materials.
The core of the automatic feeding device is arranged on the motor 423 and the throwing component 422 to feed or stop feeding under the combined action; the scheme is not a simple motor-driven feeding mode, but a special mode based on uniform feeding in the invention, and only the height of the raw material in the pre-feeding bin 43 needs to be maintained, so that the mode of uniform transportation directly driven by a motor in the prior art is completely reduced.
The transportation that carries out at the uniform velocity through modes such as motor drive paddle and this scheme's difference lies in, the paddle promotes the raw materials and is difficult to control even promotion, and is difficult to control the speed that promotes, controls the speed of pan feeding promptly.
In the scheme, the width and the thickness of the material layer to be tiled are fixed, the amount of the material layer to be tiled can be controlled by only controlling the length in each time unit, and the length is the rotating speed of the belt conveyor 1.

The rotation of the parabolic disk 4221 causes the storage tanks 4222 to overlap the pre-feeding bin 43 one by one, so that the raw material in the storage tanks 4222 automatically falls into the pre-feeding bin 43.
The scheme is characterized in that the feeding amount at one time is fixed, so that only when the subsection of the current flat material layer is required to be calculated and completely moved out of the pre-feeding bin 43, the parabolic circular plate 4221 just rotates for a certain angle, the material storage groove 4222 and the pre-feeding bin 43 are overlapped, at the moment, only the amount of the raw materials in the material storage groove 4222 is required to be equal to the subsection of the current flat material layer, therefore, the relative stability in the feeding process in the pre-feeding bin 43 can be kept, and the height is kept in a preset range as much as possible.

The gradual change speed assembly 4224 is mainly used for when the height of the chopped glass fiber material is far lower than a preset range value, the PLC control module 424 controls the motor 423 to rotate at a power higher than usual so as to quickly supplement the pre-feeding bin 43, the PLC control module 424 controls the motor 423 to rotate at a constant speed, and when the pre-feeding bin 43 supplements more raw materials, namely the pre-feeding bin 43 is short of a small amount of raw materials, the feeding speed of the parabolic circular plate 4221 needs to be reduced.
